|

Create a profile for the current user, if one doesn't already
|
|
exist.
|
|
|
|
If the user already has a profile, as determined by
|
|
``request.user.get_profile()``, a redirect will be issued to the
|
|
:view:`profiles.views.edit_profile` view. If no profile model has

**Optional arguments:**
|

|
``extra_context``
|
|
A dictionary of variables to add to the template context. Any
|
|
callable object in this dictionary will be called to produce
|
|
the end result which appears in the context.
|
|
|
|
``form_class``
|
|
The form class to use for validating and creating the user
|
|
profile. This form class must define a method named
|
|
``save()``, implementing the same argument signature as the
|
|
``save()`` method of a standard Django ``ModelForm`` (this
|
|
view will call ``save(commit=False)`` to obtain the profile
|
|
object, and fill in the user before the final save). If the
|
|
profile object includes many-to-many relations, the convention
|
|
established by ``ModelForm`` of using a method named
|
|
``save_m2m()`` will be used, and so your form class should
|
|
also define this method.
|
|
|
|
If this argument is not supplied, this view will use a
|
|
``ModelForm`` automatically generated from the model specified
|
|
by ``AUTH_PROFILE_MODULE``.
|
|
|
|
``success_url``
|
|
The URL to redirect to after successful profile creation. If
|
|
this argument is not supplied, this will default to the URL of
|
|
:view:`profiles.views.profile_detail` for the newly-created
|
|
profile object.
|
|
|
|
``template_name``
|
|
The template to use when displaying the profile-creation
|
|
form. If not supplied, this will default to
|
|
:template:`profiles/create_profile.html`.
|
|

its constructor, and it must implement a method named
